Hi,
We are using Wildfly 8.2 with JDK 1.8 on Windows 2012 Server.
We are seeing high RAM utilization by the Java Process as a result of this the OS suspends the process to make room for other process.
The heap looks very normal...it is only with Java Process memory the issue is.
Below are JVM options we have used.
-Dprogram.name=standalone.bat
-XX:-TieredCompilation
-Xms1024M
-Xmx1024M
-XX:PermSize=512M
-XX:MaxPermSize=512M
-Dsun.rmi.dgc.client.gcInterval=3600000
-Dsun.rmi.dgc.server.gcInterval=3600000
-Dorg.jboss.resolver.warning=true
-Djboss.modules.system.pkgs=org.jboss.byteman
-XX:+HeapDumpOnOutOfMemoryError
-Dfile.encoding=UTF-8
-Dorg.apache.tomcat.util.http.ServerCookie.ALLOW_HTTP_SEPARATORS_IN_V0=true
-Xms2048M
-Xmx2048M
-XX:ReservedCodeCacheSize=256M
-Dsun.rmi.dgc.client.gcInterval=3600000
-Dsun.rmi.dgc.server.gcInterval=3600000
-Dorg.jboss.resolver.warning=true
-Djboss.modules.system.pkgs=org.jboss.byteman
-XX:+HeapDumpOnOutOfMemoryError
-XX:-UseAESIntrinsics
-Dfile.encoding=UTF-8
-Dorg.apache.tomcat.util.http.ServerCookie.ALLOW_HTTP_SEPARATORS_IN_V0=true
Did not yet try with MetaSpace JVM options.
Below are some of the blogs in the forum reffered to with no exact solution..

Is there any defect with wildfly 8.2 ? Have anyone found the root cause of it ? It would be of great help..if you share your findings.
